OZONE AND CFCS

Ozone is a molecule made up at three oxygen atoms. Using energy from sunlight, it is produced in the upper atmosphere from oxygen molecules containing two oxygen atoms. In the ozone layer, which lies about 20km up, there is a balance between the amount of ozone created from 02 and the amount that returns, by natural processes, to 0;, molecules. This maintains an adequate concentration at ozone in the atmosphere to absorb the harmful UV light from the sun. Pollutants like Chloroiluorocarbons

(CFCs) have upset the balance between j

the creation and destruction of ozone by speeding up the destructive processes whilst leaving the rate 01 production largely unchanged. The breaking up of an ozone molecule by a CFC starts with a chlorlne atom breaking away from the CFC (1), and an oxygen atom leaving the ozone. Then

the chlorine joins with the loose oxygen

atom (2). Finally the chlorine rejoins with the CFC but leaves the ozone molecule broken in two. Alarmingly, the CFC is now ready to attack yet another ozone molecule, and can go on doing so for many years, progressively diminishing our protection from UV light.
